SSB is one of India's Central Armed Police Forces. It is currently under the administrative control of the Ministry of Home Affairs (MHA), Government of India. Prior to 2001, the force was known as the Special Service Bureau (SSB).
The previous role of the Special Service Bureau was to motivate and mobilise India's border population for national security during times of peace as well as war and to promote a sense of security and brotherhood among the population, in furtherance of national integration. Its present-day role consists of preventing cross-border crime and smuggling as well as other anti-national activities.
In pursuit of achieving this mandated task, the SSB has been conferred with certain powers under the Criminal Procedure Code of 1973, the Arms Act of 1959, the NDPS Act of 1985 and the Passport Act of 1967. The Government of India also contemplates conferring additional powers under the Customs Act of 1962.
These powers are to be exercised within a belt of 15 km in the states of Uttarakhand, Uttar Pradesh, Bihar, West Bengal, Sikkim, Assam and Arunachal Pradesh, running along the Indo-Nepal and Indo-Bhutan borders, as well as in any other area of SSB operation.
